For the Sony Corporation, a tech industry also-ran, the moment of reckoning is here.

The first three generations of PlayStation sold more than 300 million units, pioneered a new style of serious video games and produced hefty profits. PlayStation 4, introduced by Sony Wednesday evening, is a bold bid to recapture those long-ago glory days.

The first new PlayStation in seven years was promoted by Sony as being like a “supercharged PC.” It has a souped-up eight-core processor to juggle more complex tasks simultaneously, enhanced graphics, the ability to play games even as they are being downloaded, and a new controller designed in tandem with a stereo camera that can sense the depth of the environment in front of it.
